After the cross building and DHT11 sensor setup on Beaglebone Black

now we show how to create a C project , using the C source code available with the Adafruit library

Using Eclipse, we create a project for the reading of our sensor. It calls the functions in the C code of the Adafruit library. These sources are imported into the Eclipse project

and using the sample C code dhtSensor.c, which contains the main C program, we read the sensors by calling the funtions available in Adafruit C sources; the usage is similar to what seen in Python.

Running

./dhtSensor

1	./dhtSensor

it shows the help instructions

root@beaglebone:~/examples# ./dhtSensor
Usage:  sudo ./dhtSensor [11|22|2302] GPIOpin#
Example: sudo ./dhtSensor 11 P8_11 - Read from a DHT11 sensor connected to P8_11 Pin
root@beaglebone:~/examples#

root@beaglebone:~/examples# ./dhtSensor

Usage: sudo ./dhtSensor [11|22|2302] GPIOpin#

Example: sudo ./dhtSensor 11 P8_11 - Read from a DHT11 sensor connected to P8_11 Pin

root@beaglebone:~/examples#

To read the DHT11 sensor on pin P8_11 we have to run

./dhtSensor 11 P8_11

1	./dhtSensor 11 P8_11

The output is the following

Here is the Eclipse C project

dhtSensor Eclipse project

In the previous article we have prepared the environment with Eclipse for cross building for BeagleBone

Cross building for Beaglebone

Now we shall configure Eclipse and BeagleBone to debug the code directly on BeagleBone.

On BeagleBone install gdbserver

sudo apt-get install gdbserver

1	sudo apt-get install gdbserver

On the Debian system with Eclipse install gdb-multiarch

sudo apt-get install gdb-multiarch

1	sudo apt-get install gdb-multiarch

From Eclipse access to Run-> Debug Configurations

Double-click C++ Remote Application to set parameters

At the next window, create a new ssh connection with the New button

Enter the parameters for the connection

Set the remote destination folder for the file and execution management; with the browse button choose where to copy the files, and with the field “Commands to execute before application” will give execute permissions to the file
